libutilscallstack: removed from darwin

2019-04-01T22:16:13+00:00

libbacktrace only includes its Backtrace.cpp on the linux targets
but not windows or darwin targets. So, both should be disabled.

Previously, libutilscallstack was only ever a static library on
these platforms. Since nothing provided the symbols, these targets
couldn't have been used.

The question arose on the bug of whether this is a legit errno or just
a stale value.

libutils: Fix thread safety annotations in Mutex

The annotations for Mutex::tryLock and timedLock were
incorrectly specifying the return value for the successful
acquisition.

libutils/libcutils: make host more like device

2019-03-29T01:44:32+00:00

Having shared host libraries allows libraries depending on these to use
'shared_libs' for these. This simplifies configurations since these
libraries don't have to specify 'shared_libs' on all non-host targets.

Revert "Revert "Fix wp and sp comparison bugs""

2019-03-13T20:26:35+00:00

Fix wp and sp comparison bugs

Make clear() actually clear wp m_refs, so that nulls compare equal.

Make equality consistent with < and >, ensuring that a weak pointer
cannot be both equal to and greater than another.

Don't rely on the built-in < and > operators to correctly order
different objects. The standard does not guarantee that, and there is
a risk of compiler relying on that lack of guarantee.

Remove unnecessary comparison overloads, especially those
comparing a wp<> to an sp<>.

Change the remaining wp<> to sp<> comparisons to check for equivalence
of the mRefs pointer instead of the object address, thus eliminating
the dubious equal comparison result for a dead wp<> and an sp<> that
happen to point to the same object address.

Add comparison tests.

This reverts commit a2a2ad805775ea88f25388677aa37e0492a492c4.

The original code, and my original CL, both failed to initialize m_refs
in various wp<> constructors. This now became more important, since
comparisons now rely more on m_refs. However I believe it was always
a bug, since some comparisons always relied on m_refs.

Test: Treehugger, boot AOSP, atest RefBase
Bug: 126922090
This reverts commit a2a2ad805775ea88f25388677aa37e0492a492c4.

Reason for revert: Reapply after constructor fixes.
